Salt desorption mechanism is one of the fastest environmental actions which affects concrete structures subjected to chloride attack. 2-D numerical simulation analysis of salt desorption mechanism at concrete surface has been conducted. To conduct this numerical analysis, experimental works have been conducted to get some empirical constants. Desorption mechanisms, water thickness distribution, water velocity, and methods to measure and to calculate the amount of washed away salt are discussed and an empirical function to characterize salt desorption is proposed. |
